No True Scotsman - Climate Skeptic Edition

I wondered how LuboŇ° Motl was going to spin this result away:

Let's just assume, for a moment, that the Berkeley Earth Surface Temperature study is legit. What exactly did they find? Well, in a nutshell, global warming is definitely real. Since the mid-1950s, average global land temperatures have risen by nearly two degrees Fahrenheit. For what it's worth, this agrees very closely with previous global warming studies that were dismissed by skeptics for one reason or another. The Berkeley study also found that pretty much everything that climate change skeptics used to discredit previous studies ultimately made no statistically significant differences to the overall result.

I am not surprised:

In the video below, Andrew Revkin says that a "skeptic confirms substantial recent global warming". This is not a truly valid proposition because Richard Muller is no skeptic: realizing that Michael Mann has made things that can't be tolerated in science is nice and it may make you a heretic among some hardcore believers but it's not enough for you to be a genuine climate skeptic.
